Think about it: You are trying to make sense out of the world and people keep making gibberish sounds, hiding for no reason, showing you anthropomorphized animals and objects, telling you stories that have absolutely no point, having you play with stupid pianos that make random sounds...
Then, after they have built a model of the world containing all these nonsense, a lot of time then has to be spent having them unlearning that nonsense through discipline.
However, what if they don't get exposed to the nonsense in the first place? Or get exposed to it in a more structured way? I mean entertainment doesn't have to be nonsensical. You can learn about animals, architecture, vehicles, even simple math... instead of dumb trains with faces and teletubbies making gibberish sounds.
Btw, I am not trying to say the production of that material has no merit. I can have a lot of merit, and can be incredibly creative, it's just it could be better focused.
